I am 42 and have been having the same experience as Anon for 4.5 years in that my periods last 3 weeks - they start off normally and after about 2 days I get black dryish clotting that goes on for the 3 weeks. Then I get the start of a new period. I have had scans, internal examinations, pap smears twice or 3 times a year over period of 3 year and have been told that there is nothing wrong. The contraceptive injection does not work and neither does the pill in terms of regulating this. I have been told by a consultant specialist at my local well woman clinic that some women just bleed and that while this is fairly uncommon it does happen. The only solution I have been offered is a total hysterectomy. I don't want to have major surgery that will leave me scarred for something that is going to sort itself out naturally via the menopause. I may have to wait another 10 years though. It has made my life miserable and I wish someone could help me.
